Feelings aren’t facts — so why do they feel like it? How to weather emotional storms

From sleep deprivation to stress and hormones, countless hidden factors shape how we feel. Writer Kellie Gillespie-Wright examines the science behind mood and emotional resilience — and helps you take back control.

We all have days when we wake with a heaviness we can’t quite place, and before we have even opened the curtains that feeling begins to write a story about who we are. A flash of self-doubt, a haze of worry, a dip in energy, and suddenly your mind insists this is not simply a mood but a verdict, an instant conclusion about your worth or capability.

It’s remarkable how quickly a passing emotional state can claim the whole day, shaping how you see your life, your relationships, and your capacity to cope.

Yet a mood is far less personal than it feels. It is not a moral assessment or a window into your character. It is a temporary shift in your internal conditions, shaped by sleep, sensory load, hormones, hunger, digital saturation, unresolved stress, and the dozens of small pressures that accumulate before you even notice them.

A low mood can drift in like a change in the air, but that does not make it a permanent forecast. What you feel in these moments isn’t your identity. It is your brain and body responding to signals that arrived before rational thought had a chance to step in. Emotion begins deep in neural circuitry that evolved to protect you, not to judge you.

Neuroscientist Joseph LeDoux has shown that the amygdala can react in as little as 12 milliseconds, long before you become consciously aware of anything at all. ‘Our feelings often occur because of thoughts that happen so quickly we are not even aware we have thought something,’ explains Dr Radha Modgil, an NHS GP, broadcaster, and author of Know Your Own Power.

When the prefrontal cortex — the part of the brain that helps you interpret and regulate these sensations — is depleted by poor sleep, over-stimulation, or unpredictability, nuance becomes hard to access. ‘We are less able to engage our higher cognitive centres, which makes it harder to recognise that the triggers or causes are environmental,’ says Dr Modgil.

In these moments, a temporary shift in chemistry can present itself as personal truth, and a fleeting sensation transforms into a story about who you are. ‘Humans are meaning-making beings,’ says Kate Hogan, an integrative therapist and coach. ‘We tend to jump to a story or a judgement about how we feel, rather than just accepting the feeling as something that will eventually pass.’

When you feel low, your brain instinctively searches for an explanation for why it feels this way.

‘So a fleeting sadness or disappointment can get interpreted not just as a mood, but as evidence we are flawed.’ Dr Modgil says these interpretations often take root early in life. ‘People like to put us in boxes, and we are often labelled from a very young age,’ she says. ‘Over time, we absorb these labels as beliefs, even when there is no real evidence for them.’

When a low mood later aligns with one of those early labels, it can feel confirming rather than coincidental and ‘we start to see it as our character, rather than a passing state.’ Yet much of what shapes your emotional landscape has little to do with character at all. Research shows that even modest sleep loss can increase emotional reactivity by up to 60%.

Fluctuations in blood sugar can feel indistinguishable from anxiety, while chronic pressure keeps the sympathetic nervous system on high alert, narrowing your tolerance for frustration and uncertainty. Hormonal rhythms also play a powerful role, shifting serotonin, dopamine, and cortisol in ways that influence how resilient or hopeful you feel from one day to the next.

This is something Dr Modgil sees repeatedly in clinical practice. ‘Tiredness is a big one,’ she says. ‘When we haven’t had enough good-quality sleep, we are more vulnerable to our feelings taking over.’ Hunger, pressure, and hormonal shifts can compound this vulnerability. Rather than leaping to conclusions about what a mood might mean, Hogan encourages ongoing awareness.

‘Regularly checking in with yourself over the course of a day and noticing just how fluctuating our moods tend to be can really help.’ She suggests using the acronym HALT to check your state.

‘Ask: am I hungry, angry, lonely, or tired?’ These states dramatically increase emotional sensitivity. ‘Knowing your own cues can really help,’ she says. For some people, that sensitivity has been present for as long as they can remember. You may have grown up picking up on subtleties quickly and feeling emotions deeply. Hogan reframes this sensitivity as a strength rather than a weakness.

‘Emotionally sensitive people have the ability to feel the full spectrum of human feeling,’ she says. ‘Without these people, we would not have beautiful songs, literature, and art that moves our souls.’ When sensitivity is understood and supported, it can flourish. ‘It is possible for these individuals to learn emotional regulation and boundaries that will help them to navigate this harsh world.’

But once a mood takes hold, it is easy to believe it reflects truth. This phenomenon is known as emotional realism — the sense that what you feel now must describe your whole life. Research shows that when your cognitive energy is low, you default to fast, instinctive interpretations. Under stress, working memory also narrows. Problems seem larger, options fewer, and relationships more strained.

‘Try to see the difference between a temporary state and a character trait,’ suggests Hogan. A wave of emotion itself lasts about 90 seconds as the body processes the initial chemical response. What keeps the feeling alive is not the emotion, but what happens next in the mind.

‘What lingers is the story, the meaning, and the judgement,’ says Hogan. ‘And the story is often the more painful, lingering part.’ To interrupt that, Dr Modgil often recommends grounding. ‘Listen to something around you, smell something, look at something.’

This brings you back into the present long enough to ask, ‘What am I feeling? What am I thinking? Is it true?’ As she explains, ‘Feelings have a momentum about them,’ but they lose force when you slow them down.

When that momentum is not interrupted, it often spills beyond the inner world and into behaviour. A mood begins to fuse with identity, and your actions contract around it. You cancel plans, retreat from people who might help, and assume you will be a burden. ‘Often when we feel vulnerable and “less than”, we do not want to connect with or be seen by others, when that connection is often the exact balm we need,’ says Hogan.

She suggests beginning with nervous system regulation, using breathwork or self-touch to soften the body’s alarm response before trying to think your way out of the feeling. Practices such as ‘havening’ — ‘a type of self-touch that really helps to soothe the overwhelm’ — can restore enough calm to widen perspective.

From there, having a simple plan helps. ‘Perhaps identify a few safe people to reach out to, or an activity that can open us up to connection rather than closing us down.’

This approach rests on a more helpful understanding of mood itself, as an internal condition that rises and falls rather than a statement about who you are.

Hogan also teaches the EBTA process — E for emotion, B for body, T for telling, A for action — which encourages small, steadying steps when emotions run high.

‘The idea is to keep it small,’ she says. Dr Modgil suggests becoming curious when a reaction feels bigger than the moment itself. ‘When it feels out of proportion, that in itself is a red flag that there may be an underlying emotional pattern or past hurt being activated.’

In those moments, she encourages turning first to simple, human forms of care. ‘Do you need a cup of tea, a hug, a cry?’ Over time, this kind of attention lays the foundation for steadier emotional ground. As Hogan puts it, ‘It is about finding a blend that works for you — anything that helps with self-awareness, nervous system regulation, and builds self-compassion.’

Dr Modgil also points to habits that help you respond thoughtfully rather than react automatically. ‘Meditation and mindfulness allow us to get familiar and in touch with our feelings rather than being pulled into them.’

Time spent outdoors can play a similar role. ‘The natural world is usually fairly peaceful and in balance, and this gives us a template for our own emotional balance.’

Compassion binds all of this together, not as an abstract ideal, but as a practical way of meeting yourself when emotions run high. Hogan often asks clients how they would speak to someone they loved.

‘I can bet it would be with a lot more kindness and generosity than they speak to themselves.’ She recommends Kristin Neff’s exercise of writing a letter to yourself ‘from the perspective of a loving friend.’

Over time, meeting yourself in this way begins to change your relationship with your moods altogether. They are no longer experienced as instructions to follow or definitions of who you are, but as passing experiences within a much larger sense of self. As Hogan puts it, ‘Your moods make up a part of you, but are not your entirety.’

With that shift, moods lose some of their authority. You notice a feeling without immediately asking what it says about you, attend to the body, let the nervous system settle, and allow the story to wait. Some mornings still feel heavy, and some moods still arrive without explanation, but they no longer carry the same weight.

They are part of being human, not a verdict on who you are. When you stop treating your internal weather as a personal appraisal, a steadier, kinder understanding of yourself begins to grow — one that allows emotional life to move as it must, while you remain stable.

How to Steady Your Mood Now, and Strengthen It Over Time

Name what you feel

Labelling your feelings reduces emotional intensity by engaging the brain’s reasoning centres. Try simple phrases such as ‘I notice frustration’ or ‘I can feel my energy dip’.

Check the basics

Hunger, dehydration, poor sleep and sensory overload often imitate emotional collapse. Before you draw conclusions, ask what your body might be signalling.

Slow your breath

A long, steady exhale supports the vagus nerve and calms the nervous system. Five or six slow breaths a minute can ease intensity within moments.

Anchor in the present

Place your attention on something physical, like your feet on the floor or your hands on a surface. Grounding interrupts rumination and brings you back into your body.

Move to shift chemistry

A short walk, stretching or simply standing to change posture alters neurochemistry enough to help a mood settle.

Create a pause before reacting

Give yourself a few seconds between feeling and behaviour. A pause disrupts the chain reaction that turns a mood into a self-defining story.

Grow your emotional vocabulary

The more precisely you can name a feeling, the more effectively you can regulate it. Words like irritated, worn down, restless or disappointed bring clarity and reduce overwhelm.

Track patterns

Notice when and where your moods tend to shift. Sleep cycles, hormones, work pressure and social contact all shape your internal landscape. Recognising patterns replaces shame with insight.

Journal briefly each day

A few lines about how you felt, what influenced it and what helped you recover strengthens emotional processing and highlights repeat themes.

Build micro-rest into your routine

Short breaks, sensory resets and changes of scene prevent the gradual accumulation of stress that often drives mood swings.

Set boundaries that protect your attention

Consistent limits with screens, work and relationships reduce over-stimulation and support steadiness.

Act from values, not impulses

Notice your first reaction, pause, then choose the action that reflects the person you are, not the moment you are in. Repetition strengthens regulatory pathways in the brain.

Prioritise restorative basics

Regular sleep, movement, hydration and balanced nutrition provide the biological foundation for stable mood regulation.
